GrAS BURNER.

Application filed May 13,

T 0 all ham it may concern Be it known that I, HUBERT R. HUMPHREY,

a citizen of the United States, residing atwhich I have used the same in my application for Letters Patent Serial #339,917, filed Nov. 22, 1919, one form of my burner improvements as illustrated in this application being illustrated in such application.

The main objects of this invention are First. To provide an improved burner having aplurality of aligned burner tips in which the gas is quite uniformly delivered to the several tips.

Second. To provide an improved gas burner of the multiple tip type having the above advantage, which is simple and economical in structure and not likely to get out of repair in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawings, forming a part of this application, in which:

Fig. I is a front perspective view of a gas heater embodying the features of my invention, a portion only of the radiants being illustrated.

Fig. II is a detail vertical section on a line corresponding to line 2-2 of Fig. I.

Fig. III is a fragmentary viewpartially in longitudinal section through the burner on a line corresponding to line 3-3 of Fig. II.

Fig. IV is a fragmentary sectional view corresponding to that of Fig. III of a Specification of Letters Patent.

1921. SerialNo. 469,138.

slightly modified form or embodiment of my invention. 7

Fig. V is a fragmentary section corre sponding to that of Figs. III and IV of another modified form or embodiment of my invention, the section being on line 5-5 of Fig. VI.

ig. VI is a transverse detail section on a line corresponding to line 6-6 of Fig. V.

In the drawings similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the base 1 is provided with an upwardly projecting arm or standard 2 carrying a pivot 3 for the arm 1 of the heater body 5. Within this heater body is a fireback 6, in front of which are arranged the radiants 7, the heater body being provided with openings 8 with which the radiants are aligned to receive the tips of my improved gas burner.

My improved gas burner, the body of which is designated generally by the numeral 9, is provided with a cylindrical manifold chamber 10 and internal annular rib-like partition members 11. These ribs are preferably irregularly spaced, the purpose of which will appear as the description proceeds. Fitting within these ribs is a tubular screen 12forming with the ribs a plurality of annular discharge compartments 13 opening through the screen into the manifold chamber. The burner tips 14 open into these compartments or open between the ribs. A Bunsen tube 15 projects'into the manifold chamber and preferably discharges adjacent the outer end thereof, as shown in Fig. III. A yoke-like bracket 16 is provided for supporting the nozzle 17 in alignment with the Bunsen tube. 18 represents a nipple to receive the gas supply connection.

The burner is provided with theopening 19 at its outer end through which the screen .may beintroduced and removed, the closure 20 for this opening also serving as a support for this screen.

By this arrangement of parts the gas is quite uniformly delivered to the several Patented Aug. 8, 1922.

burner tips and one tip does not rob the adjacent tips. The ribs are preferably irregularly placed, those at the outer end being disposed to make smaller discharge chambers than those at the inner end, as the pressure of gas is greatest at the discharge end of the Bunsen tube. However, very satisfactory results aresecured where the ribs are uniformly spaced, as the tendency of one tip to rob another is quite effec tively overcome.

i In the modification shown in Fig. IV the partition members 2lserving the purpose of the ribs 11 are in the form of rings and may be 'eitherfitted within the manifold chamber to receive the screen or fitted on the screen and then slipped into the chamber.

In the modification shown in-Figs. V and V I the body '22 of the burner is semi-circular in cross section, having a movable top plate 23 with partition members 24 thereon coacting with the flat screen 25 providing a serles of discharge compartments 131 My improved burner s very effic ent and as stated, the tips are very uniformly supplied with gas, and the parts are simple and economical to produce and not lilzelv to get out of repair in use. i

Having thus described my invention 7 what I claim as newand desire to secure by Letters Patent, is

1. In a ga s burner, the combination of a body member provided with a cylindrical manifold chamber and internal annular ribs irregularly spaced therein, a tubular screen arranged in said manifold chamber and coacting with said ribs to provide a plurality j of annular delivery chambers of different 4O capacities, burner tips mounted on said body member opening into said delivery chambers, the outer end of said body member being'open to receive said screen, a closure for said opening on which'tbe outer end of said screen 1S mounted, and a Bunsen tube projecting into said manifold centrally of said screen and discharging adjacent the outer end thereof. 1 v j 2.
